Rock Golem Concept

I am a Game Art and Animation major interested in concept art and put this together over the weekend. Wondering if there any suggestions for the overall creature and any sort of problems that I could correct.

There are some structural issues/rendering issues/how does he move issues, but the thing that stick out to me is how little I think of "rock golem" when I look at this piece. He looks like an armored preying mantis kind of creature that's been... mixed with a lizard?

"She took the ice cube trays out of the freezer. What kind of a sick bitch takes the ice cube trays out of the freezer?"

Rock golem is poorly named, but it's the only thing I could come up with at the moment. He is very top heavy, but I wanted a pose that showed the entire figure. He actually walks on his hands similar to that of a gorilla.

the torso looks really flat, kind of like a horned lizard or something. not anything I would trust putting all the weight of those arms on. Those arms look far too huge and cumbersome to actually move around on them. If he is supposed to walk around like a gorilla, why not put him in that pose? It could tell more about the character. Then you could use gorilla images for reference as far as proportions with the arms goes. Try drawing the complete tail, it looks like its chopped off and floating behind him, it doesnt connect at the proper place.

i'm having trouble reading him as "top heavy" when he has no shoulders to speak of, and when his chest area seems to be merely well-armored, but weak. also, the different sections of the armor aren't melding together well at all- i'd suggest maybe fleshing out the basic shapes (i.e. reducing the armored section to a few blocky shapes that make sense to you as a silhouette/basic figure) and then adding in the details?
